Let's assume you know what you need and why you need it. Does http://www.soft32.com/Download/Free/RAS_Async_Adapter/4-170548-1.html help? It says it's OS supplied, so it should be on the XP CD, but, well, this might be useful.
However, also read through http://forums.techguy.org/web-email/373432-outlook-ras-async-adapter-what.html
It casts some doubt about the possible issue, I'd say.
I need a driver for my network card - a RAS Async Adapter. Can't seem to find a proper download anywhere on the net! Not even on Windows Update! Any help appreciated!
